1.1.1.1 + WARP: Safer Internet

1.1.1.1 + WARP: Safer Internet is a service that encrypts Internet traffic leaving a phone and provides options for filtering DNS requests. Using a modern, optimized protocol for the Internet connection, the app combines network-level encryption with configurable DNS filtering to address privacy and security concerns.

The core function is straightforward: the app encrypts all traffic leaving the device, protecting Internet activity from observation between the phone and Cloudflare's network infrastructure. This network-level encryption affects all applications and websites accessed through the device, rather than operating at the application level. By default, the app uses Cloudflare's standard DNS resolution service, which translates domain names into IP addresses.

For users wanting additional filtering layers, the app includes an optional "1.1.1.1 for Families" DNS setting that blocks requests to domains associated with malware, phishing attempts, and cryptocurrency mining operations. This DNS-level filtering prevents connections to known problematic domains before they are fully resolved. The service makes no distinction between intentional and unintentional access attempts—blocked domains simply fail to resolve, preventing any connection attempt from completing. Users can toggle between standard DNS resolution and this filtered mode depending on their current needs.

Setup requires minimal user interaction. The initial configuration is a one-touch process, allowing users to begin encrypting their traffic without navigating multiple menus or complex authentication flows. This straightforward onboarding extends to the app's settings, where toggling between the standard DNS service and the "1.1.1.1 for Families" filtering option is similarly accessible.

The app operates on a freemium model. The base encryption service is available at no cost, providing standard traffic encryption and DNS resolution. A subscription tier called WARP+ adds unlimited data capacity, removing any data caps that might restrict encrypted connections. WARP+ subscriptions renew automatically each month unless explicitly cancelled at least 24 hours before the billing period ends. This cancellation window is a specific contractual requirement—cancellations submitted after the 24-hour threshold will not prevent the upcoming renewal charge. If a user cancels a subscription after starting a free trial period or while possessing unused data credits from a previous promotion, those benefits are forfeited upon conversion to a paid subscription and cannot be recovered or transferred.

For users on familiar networks, the app includes a Trusted Networks feature that recognizes known networks and adapts device behavior accordingly. Enabling this feature requires opting into precise location sharing through device settings, as the app needs to identify the device's location to determine which networks are familiar. The feature also requires access to the network name (SSID), allowing the app to recognize specific wireless networks by their identifier. On Android devices, this feature improves compatibility with home devices like printers and televisions that may have specific network requirements or expectations about traffic patterns and connection stability.

The underlying technology relies on a modern, optimized protocol designed to maintain connection quality while encrypting Internet traffic. This affects both connection speed and latency, with app performance varying based on network conditions, geographic location relative to Cloudflare's infrastructure, and device capability.
